Thulium Electrons per Shell (Tm) [& Color, Discovery ... 2022

Atoms have electrons that need to be distributed somehow, even Thulium. Ok so where are these electrons in an atom of Tm?

In the case of Thulium the number of electons per shell is 2,8,18,31,8,2. Besides the distribution of electrons there is a lot of funny facts about Thulium that most don't know. Let me show you...
